| Best for | Custom-fit home sewing patterns | Using construction codes without treating classification as a machine setting, material assignment, supplier translation, or performance guarantee | Learning or comparing knit structures |
| Know before using | A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. | A foundational library, not yet an exhaustive stitch encyclopedia. |

| What the source establishes | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. | The guide cites the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025), plus current seam-failure and seam-tensile methods; it keeps classification, translation, complete process definition, physical verification, and performance evidence separate. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. |
